existence is a weird thing, in the sense that it becomes infinitely valuable when it doesn't have an end point, and more or less useless when it does. worse, it's value degrades as one ages.

somebody did the math on about 4 years per twelve years of smoking. i'm not convinced that adding an extra fifteen or twenty years to the end of my life sounds like a good idea. 85 or 65? i'm not really looking forward to the quality of life that accompanies most people in their 60s and 70s, whether they're smokers or not.

i'd rather suggest that the opposite message is more valuable. you don't have infinite seconds to waste being distracted by neon-flashing lights. you've got a few decades to accomplish something, then you become somebody's burden and finally end up recycled back into the biosphere.

if smoking a cigarette helps you focus a bit better on what you're doing, or keeps you awake a few hours longer while you're working on something important to you, it's worth the cost of a few less years in the old folks home.

it's expensive, though. keep that in mind.
